Donna, depending on how long it takes to get off the ship and go through security, I will have about 7 hours. I am guessing that is enough time for the Dolphin Cay excursion (3 hours), which includes the Ruins Lagoon, a beach, and shallow water interaction with a dolphin. If there is, that will be the highlight of my cruise. I probably am cutting it close. If there is not enough time for both that and Discover Atlantis and Harbor Cruise, let me know. Supper is at 8:15 in the traditional dining room.
